1. Thorough Cleaning and Draining
1. Removing Residual Starch
Disassemble all removable components of the separator (such as the filter, cyclone tube, and drum), and flush the interior and piping with a high-pressure water jet to prevent residual starch from fermenting and spoiling.
Place special attention to cleaning the filter and drain screen to prevent starch from clogging the filter pores. Ensure that no black, sticky residue remains before long-term decommissioning.
2. System Draining
Drain all liquids (including starch emulsion and rinse water) from the separator to prevent accumulated water from corroding the equipment or breeding bacteria.
2. Protecting Key Components
1. Lubrication and Rust Prevention
Apply food-grade lubricant or rust-proof grease to moving metal parts, such as bearings and chains, to prevent oxidation and rust during decommissioning.
Stainless steel parts can be coated with a small amount of cooking oil to form a protective film.
2. Seal Inspection
Inspect gaskets and rubber strips for deterioration. Replace damaged parts and apply silicone grease to prevent seal failure. 3. Storage Environment Control
The equipment should be stored in a dry and ventilated area to prevent moisture from contaminating the circuits or mechanical components.
A dustproof sheet should be used to prevent dust from entering the separation chamber or transmission system.
4. Regular Maintenance and Inspection
Every three months, power on and idle the equipment (such as motors and pumps) for 5-10 minutes to prevent component seizure.
Check the oil level in the hydraulic system to ensure that the hydraulic components are in standby mode.
5. Preparations for Restart
After reassembly, perform a no-load test run to confirm that there are no abnormal noises or vibrations.
Before the first batch of feed, circulate clean water through the system to prevent residue from contaminating the starch.
